Features:
– With voltage, current, and power display, it can be easily used without a multi-meter.
– With ∪ SB interface, with 3 major functions, to meet most of your occasions!
– High power, high efficiency, 5A, low ripple
When used as a lithium battery charger, you can set the float voltage and charge current.
Is it charging or already full;
– It has a current limiting protection function, which will not burn the module even if the output is short circuited.
– The onboard voltage and ammeter can be self-calibrated, and there will never be an inaccurate problem.
Three Major Functions:
(1) Used as a normal step-down module with overcurrent protection capability;
(2) Used as a charger for various voltage lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs).When used as a lithium battery charger, you can set the float voltage and charge current.
For solar panels, wind turbines, etc.;
(3) used as a high power LED constant current driving module;
Specifications:
Input voltage: 5-36V
Output voltage: 1.25-32V continuously adjustable
Output current: adjustable, up to 5A (recommended for use within 4.5A)
In the middle: Gu Da Li (internal use.
Working frequency: 180KHz
Conversion efficiency: up to 96%
Short circuit protection: Yes
Over temperature protection: Yes (automatically turn off the output after over temperature)
Input reverse connection protection: None (if necessary, please input a large current diode in the input string)
Installation method: 4 3m silk
Wiring method: terminal block or soldering terminal, ∨-for input, ∨OUT for output
Size: 68.2×38.8x 15mm
Application Range:
1.As a pass-through buck module with overcurrent protection
Instructions
(1) Press the right button to adjust the digital meter to the [display output voltage] interface, adjust the "constant piezoelectric device"
To make the output voltage reach the voltage you want
(2) Adjust the digital meter to the [Display Output Current] interface and directly short the output of the module (find a thick strip)
The wire can be shorted to the output end. At this time, adjust the "turbulent potentiometer" to make the current value on the digital meter reach the pre-
Set the overcurrent protection value; (such as the current value displayed on the onboard ammeter is 4A, then the maximum current of the module is
Limited to 4A, the red indicator light is on when the current reaches 4A)
(3) Connect the load and work.
2 used as a battery charger
Modules without constant current function cannot be used to charge the battery, due to the exhausted battery and charger
The pressure difference is very large, causing the charging current to be too large, causing damage to the battery, so use the battery at the beginning.
Constant current charging, automatically switch back to constant voltage charging when charging to a certain extent
Instructions
(1) Determine the float voltage and charge current of the battery; (if the lithium battery parameter is 3.72200mAh, then
The float voltage is 4.2V and the maximum charge current is 1C, which is 2200mA.
2) Adjust the digital meter of the module to the [display output voltage] interface under no-load conditions, and adjust the "constant voltage"
Potentiometer" causes the output voltage to reach the float voltage
(3) Adjust the digital meter to the [Display Output Current] interface and directly short the output of the module (find a thick strip)
The wire is shorted to the end of the wire), at this time adjust the "constant current potentiometer" to make the current value on the digital meter reach the pre-
Set the charging current value;
(4) The charging lamp current defaults to 0.1 times the charging current; the battery is gradually reduced during the charging process.
Small, gradually changing from constant current charging to constant voltage charging, if the charging current is set to 1A, then when charging
When the electric current is less than 01A, the blue light is off, the green light is on, and the battery is charged.
(5) Connect the battery and charge it.
(Steps 1, 2, 3, and 4 are: input terminal is connected to the power supply, and the output terminal is not connected to the battery.)
2. Used as LED constant current drive module
(1) Determine the operating current and maximum operating voltage that you need to drive the LED
(2) Under no-load conditions, adjust the digital meter to the [display output voltage] interface and adjust the "constant piezoelectric positioner".
Making the output voltage reach the ED operating voltage;
(3) Adjust the digital meter to the [Display Output Current] interface and directly short the output of the module (find a thick strip)
The wire is shorted to the end of the wire), at this time adjust the "constant current potentiometer" to achieve the current value on the digital meter
Preset LED operating current;
(4) Connect the LED and test the machine.
(Steps 1, 2, and 3 are: input power supply, Han out no LED light)
Package Included:
1 x Step Down Power Supply Module with Display and Shell
